Why does an ammeter have a low resistance while a voltmeter has high resistance?

Voltmeter measures in parallel. Low resistance would cause significant current flow through the meter and load the measured circuit - which could cause erroneous readings.
The ammeter, on the other hand, measures current flow in series with the balance of the circuit - so low resistance would be best so it doesn't load the circuit.
